Azure Data Factory - Read binary byte content

I have multiple binary files in azure blob storage that I need to read and parse content. Problem is that it not a csv file but a binary file with dynamic content. I have c# code to read the file and parse content into class but have no idea how to integrate that in ADF

As you already have the c# code to convert the byte to csv. By considering all the challenges related to 5 in timeout and delay in processing. I would recommend to try the following.

For this you need to expose your C# code as an API and it should be triggered upon an api call.

As soon as the binary files get uploaded to blob, leverage Blob Event Trigger and route the message to your custom api trigger. Which should get the binary file from blob then parse (take own time) then store it back in blob again. If you are able to do this then you can access the parsed file from ADF instead of binary file.
